[movies]Ionization Energy (Second Edition) - CHEM Study, College of Chemistry and Lawrence Hall of Science, U.C. Berkeley
Two methods of measuring ionization energy, photo-ionization, and electron bombardment, are shown. A high vacuum system is used with a simple cell to measure electric conductivity of gases. The photo-ionization of sodium by the use of a mercury light source and a monochromator is carried out. The electron-bombardment method is then demonstrated with sodium and three noble gases. Animation shows what occurs on the atomic level during the ionization process...
